Display panel of an electronic personal training device with a transitional graphical user interface



FIG. 1 is a front elevational view of a first image in a sequence for a display panel of an electronic personal training device with a transitional graphical user interface showing my new design.

FIG. 2 is a second image thereof; and,

FIG. 3 is a perspective view of the image of FIG. 2, shown on a personal training device.

The appearance of the transitional graphical user interface sequentially transitions between the images shown in FIGS. 1 and 2. The process or period in which one image transitions to another image does not form part of the claimed design. The broken lines shown in FIGS. 1 and 2 illustrate portions of the display panel of an electronic personal training device with a transitional graphical user interface that form no part of the claimed design. The broken line showing of a personal training device in FIG. 3 forms no part of the claimed design. 

CLAIM The ornamental design for a display panel of an electronic personal training device with a transitional graphical user interface, as shown and described.
